Problem• Deteriorating Pavements
– More traffic, trucks, buses– Less funding available– Road materials are more
costly– Useful life of materials
seems shorter
Answer
• Do nothing (doesn't work)
• Repeat last years approach (again & again)
• What is the industry doing?
Why Micro PAVER?
• Developed by the Army Corps in the late 70’s•Recommended by APWA (American Public Works Association) •Optimizes funds allocated for M&R• Utilizes the PCI methodology• PCI became an ASTM standard in 1999• Most widely used system in the world.

Pavement Management
• Plans, Organizes & Documents
• Helps make better decisions
• Provides support data for decisions
• Answers what if scenarios
• Objectively answers “what can be left out”
• Shows the progress or lack of
• Objective recommendations
What is a Pavement Management System? (Micro PAVER)
• Inventory
• Inspection (ASTM)
• Reporting
• Modeling
• Condition Analysis
• M&R Planning
Inventory
• Street Name (block - to & from)• Length, width, area• Type of pavement (asphalt, concrete, etc.)• Rank (arterial, collector, residential, bus
route)• Last const. date• Zones• Other Items
Sections
Numbered: West to East & South to North
Inspections
• ASTM (American Society for Testing and Materials)
• Objective• Distresses• Severity• Quantity• Feet on the ground• Data must be correct Training & Dedication is
essential • Micro PAVER produces a PCI (Pavement Condition
Index) 0 to 100
Inspection Procedure (Alligator cracking)
Reporting, Analyzing, Planning
• Graphs, Bar charts, Maps– Where you are now– Where you can be– Where you will be
• How to get there– Funding– Value of Preventive Maintenance
$ Savings
• Utilizing a Pavement Management System will save a minimum of 10 %.
Pavement Deterioration
$1.00 for preventive maintenance here . . .
$5 to $7 for Severe Maintenance Repair here… or several years of pothole patching if money is short !

Micro PAVER Provides
• A Plan that can be explained
• Documentation to support the Plan
• Reinspection to confirm the Plan is on track and working
• Objective before and after comparisons (responsibility)
• A format to test new ideas
Micro PAVER vs Dump Truck (or resurfaced street)
• The Micro PAVER is an investment in a new way of solving problems.
• It provides the documentation to direct and justify decisions to provide savings.
• This is an investment into having a better street system.
• The dump truck or resurfacing is gone in several years with minimal lasting benefit for the system.
When Funding is short
• The Best decisions need to be made • Best treatment - best street - best time• More Documentation is needed for
reasonable explanations– More public inquires are a certainty
• Illustrations of just what is the result will provide sooner refunding
• Be Proactive (something can be done)
Micro PAVER can produce
• A listing of Streets to be Treated in the next 3 – 5 years.
• Understanding that there are variables that could modify the list (up or down).– Funding, severe weather, material costs, changing
traffic patterns
• The list will include:– Preventive maintenance, routine maintenance and
severely deteriorated street repairs (good, fair & bad) “A Balanced Program”
